Some of them are purposefully omitted when they should be there, but some like Brinstar, Norfair and Escape have special Fxx commands at the end.
On the contrary, some OSTs have truncated frames e.g. Action 52. They are also called irrational tempi, given the time interval is sufficiently long, in this case, infinite.
Oh gee, I'm contributing productively to this topic.
I'd just like to know if you guys notice any difference between these two NSFs. I did that cover long ago. The original (P-13.ftm) uses speed 3 with tempo 180 all along; the second version (P-13_speed.ftm) uses tempo 150 with speed constantly switching between F02 and F03. I'm playing them both in sync as I write this, and I can hardly hear any difference. If anything, I think using speed changes all the time makes the arp on square 1 sound worse than using 360 BPM.
So yeah, I'd like to know what you guys think, and if you reckon my use of 360 BPM in the original version affects the overall quality of my cover.
No quality difference. Though I haven't done the math, I have a sneaky suspicion that 180 is coincidentally a tempo that leads to an integer of frames per row.
The only thing I hear is when you isolate 2A03 sq 1, on pattern 01 there's more clickiness in the 180tempo for the first rows up to 2C. But that's only when isolated. I still haven't worked out the math for different tempi and nicetas' formula is confusing for me.
Oh, you're at speed 3, well, it'll do alternating 3s and 2s (not sure which will come first though), so it'll be the same or almost the same as your other one.
Here's the math behind it.
In NTSC, Tempo = 3600/x (x = frames per quarter note)
3600/20 = 180
So 20 frames per quarter note gives a tempo of 180.
This song uses 8 rows per quarter note.
20/8 = 2.5 -- so each row lasts an average of 2.5 frames.
So Famitracker is already alternating between 2 and 3 frames every row (the same thing that you did).
The thing is, every integral tempo is accessible from 150bpm by adjusting the speed value, and it is the only bpm where speed = frames per row. It makes it crystal clear when you need to care about frames (when making timed envelopes and arpeggios, etc.) You could look it up in a chart, but all of them are available as various speeds of the 150bpm option.
But I mean, as a start, at four rows per beat, you get this from various frames per row:
This chart is assuming 4 beats per row, so the max/base tempo at speed 1 is 3600/4 = 900. The subsequent speeds are just dividing from 900.
Maybe you want 3 or 6 beats per row, or something else, start again at the top of the column by dividing it from 3600.
Another way to pick your integral tempo, say you want something close to 87bpm. 900/87 = speed of about 10.3, so your two closest options are speed 10 (90bpm) and 11 (81.8ish).
